What is the most effective way to practice solving puzzles in order to improve`?

@achja Did I improve my game? Yes. Standard helped initially, but it took to much time and was inefficient. Blitz helped more. I also learned how to play blitz, prior to that I was always too slow and lost on time very often. Now I can really speed up if necessary and win won positions instead of getting flagged. But tactics are not everything. I am really into getting better at strategy/positional play at the moment, that's something I can really improve at.

@teerdurchzogen

I remembered an example where common sense and calculation saved the game lichess dot org/1KdCQNaQ#52
This was on stream from IM Alex Astaneh. He had been telling the viewers a few moves earlier that the opponent did not have the Anastasia checkmate because queen and knight could block (Nh3).
And around there he almost gave his opponent an immortal game (More or less Alex his words) by grabbing Nxh8 allowing Ne2+ and Qxh2+ and then Rxh8+ after which the white queen is helpless.

Regarding your #10 I see your point, and appreciate it, and maybe I am too much focused on OTB chess improvement.
I remember that a few years ago GM Dlugy commented on a forum post of mine (on another web site) that blitz really helped to improve his chess !
So, maybe for you and the OP of this post blitz tactics can help for your blitz games, still for myself I tend to think that real chess improvement goes more like Jobava (great interview, search with a search engine for Jobava and chessbase) and Bosboom do, solving puzzles with a wooden chessboard slowly.
Perhaps some more scientific research on chess improvement could help us all.

@Tae7 solve easy ones fast and hard ones slow. this is my advice.

I think people are putting too much faith in puzzles because of the difference in conditions. In a puzzle you know there's a winning tactic there because that's the whole point, you don't have that in actual game.

@achja On move 27 you mean. Yeah, that would have been nice indeed.
I haven't yet played OTB chess, so I cannot really comment on that. But I have read the Jobava interview some time ago and I reread the ifrst part of it now, after you've mentioned it. He says solving studies and stuff is very important, and I assume he is right about that. But we are not talking about really strong players here, 2000 FIDE +, we rather need to learn basic patterns and calculations first, then slowly move on to harder and harder ones. Good puzzle books like "Improve Your Chess Tactics" by Neishtadt are likely to be a good companion to the blitz mode on chesstempo. If that has to be done on a wooden board or not? I think if the positions are really hard and you are tired of staring at a screen: sure, that could be an idea. Also if you want to focus on OTB improvement you might as well study more with a board, that sounds sensible. Personally I really like to work with my desktop pc though. I can use the lichess analysis board (with SF) to look at different possibilities, to understand even the last intricacies of a tactic/position (after having thought about the problem and the solution myself), and I couldn't do it like that on my own. For instance I am working on a strategy book with lots of examples, and I could follow the main line and be content with that, sure, but I always wonder about other parts. So I scan the positions with an app, create a lichess study and look at the position deeply (or broadly/widely). I have read the book I work with is recommended for stronger players than me. Well, I think I can get a lot out of it, but I would struggle much more if I could not use an engine helping me. So that (and the time it needs to set up the board) are good enough reasons for me to not use my wooden board that often. But: I am learning all the time, and my approach changed a lot over the years, so I will see how playing OTB will alter my approach once again.
To get back to the topic a little more once again: I think those tactics help for most online time controls, also should have a positive effect for OTB until a certain point at least. If one cannot solve basic calculations easily, it's questionable if the time invested in solving long calculations is efficiently used.

@stumilowylas Me: practices amlost daily and is an absolute patzer
2000 rated player: "I don't really focus on improving my chess"
WHY IS LIFE SO UNFAIR LOL
Seriously, you are really good :)

#2 Same here. I only started taking chess more seriously since lockdown.Before then I was a complete noob xD

@achja Thanks for your insightful comments! I will definitely checkout chesstempo :) I also found your exchange with @teerdurchzogen instructive as I’m relatively new to chess studies lol. You are right about dealing with ‘Tilt’, I solved a couple of puzzles today not under time pressure,with a clearer head and my rating is kinda back to ‘normal’ (though I don’t care much about puzzle ratings) Just out of curiosity, how long have you been playing chess?

@xPhilosophusx Absolutely!

#14 True to a certain extent, but I expect it will improve calculation skills and pattern recognition in the long run.

@Tae7

In order do these...

• Make sure no issues with basic linear and basic Knight visualization.
  For exercises see:

  https://lichess.org/study/jftL3ptX

• For each basic tactic

• Do "deliberate practice" on that tactic to help internalize it.
  For an example of what that means, see this example for "pin":
  https://lichess.org/study/wzFrgluQ/idQPqUJu
• Do puzzles of that tactic.
  Start slow and build up to the speed you normally play chess.
• Do random puzzles across basic tactics.

Repeat the above training for more advanced tactics and combinations of tactical ideas.

@Tae7
Cheers, nice to hear you have dealt with tilt mode well.
I've joined an otb chess club for the 1st time around about 1985. Lost the first 10 games or so, then won my 1st game and kept on learning about chess.

Oh I wasn't born rated 2000 dear @kertandidi ! I did solve thousands of puzzles throughout the years and played many games. I spent (wasted?) a considerable amount of time on chess. By not being serious I mean it was never a competitive sport. I'm not going to hire a coach or anything, I just like puzzles.
